Specification of Letters Patent. Patented Feb. 25, 1913.

Application filed March Z, 1910. Serial No. 547,676.

. To all whom it may concern:

Be it known that I, EUGENE A. 'lnnrxni, a citizen of the United States, residing at Batavia, in the county of Genesee, State of New York, have invented certain new and useful Improvements in Pasteboard-Box Machines, of which the following is a specification.

This invention pertains to machines used in the manufacture of pasteboard boxes, and relates more particularly or more especially to an appliance of this character for securing the heads in the rims or bodies of the boxes and covering the latter with paper, the two edges of which are folded into the box and over the head, respectively.

One of the main and leading objects of the invention is the production of a machine of this character which will assemble the parts of a box with great rapidity so that the boxes can be produced at high speed and with a maximum of economy.

The-invention is particularly useful in the manufacture of rectangular or similar boxes having the sides or rims disposed at an angle one to the other as distinguished from machines of this kind used for the" production of round pill boxes, but it will be readily understood from the following detailed description of this machine that the same is also adapted, with slight modification, for the production of the round bo'xes referred to.

In order that a full and complete understanding of the invention may be had, I have illustrated a preferred and desirable embodiment thereof in theaccompanying drawings, throughout the various views of which like reference characters refer to the same parts.

In these drawings-Figure is a fragmentary end elevation of a machine embodying this invention; Fig. 2 is a plan view of the machine; Fig. 3 is a fragmentary rear elevation of the machine; Flg. 4 is a fragmentary front elevation of the machine with many parts omitted; Fi 5 is a vertical section through the mac ine showing the means for applying the bodies or rims to the form and illustrating the manner of wiping the glued paper down on to the head or bottom of the box; Fig. 6 is a perspective View of one of the rods carrying the cams for operating the wipers shown in Fig. 5;

Figs. 38, 39. and 40 are fragmentary sec-- the'outer end of which next to the bearing and held by a suitable collar-.54 is aslotted element 55, Figs. 1, 2, and 4, formin one part of a Geneva movement. As is cliearly indicated in Fig. 4, this element 55 is of disk form, having four radially-extended slots 56 disposed 90 apart, the periphery of the member or element between the slotted portions being concave at 57 forthe accommodation of the convex or curved part 58 of the other element 59 of the Geneva movement fixed to the shaft 60 disposed below'and in the same general direction as.

the shaft 53. This second member 59 has a v cut-away portion or concave recess 62, and 40 element 55, causing step by steprotation of.

the shaft 53, each movement being through an arc of 90. As this form of mechanism is well known, it will be readily understood that the shaft 53 is held or locked in its various positions by the entry of the convex portion 58 of the lower member 59 in one of the concave recesses 57 of the upper member "By this means the shaft 53 is rotated step by step through arcs of 90, although this lower shaft 60 rotates at a constant speed. This shaft 60 is rotatable in suitable bearings and has keyed or otherwise fixed thereto a gear 66 meshing with the teeth of which is an intermediate gear 67 suitably mounted on the table, this latter gear in turn meshing with another characterized 68 and mounted on a short shaft 69 rotatable in bearings 70 bolted to the top of table 50, such shaft 69 also having fixed thereon a slightly larger gear 71, the teeth of which in turn are in mesh with those of another gear 72 rotatably mounted in any approved manner on the under side of the table, it being understood that such table is slotted at 73 for the proper accommodation of the above mentioned gears and the lower elements of the Geneva movement referred to. Gear-7 2 meshes with another 74 0-11 an end drive shaft 75 below one end of the table and revoluble in a pair of bearings 76 and 77 bolted or otherwise conveniently fastened to the under side of table 50. Asis shown in Fig. 1, this gear "(at is maintained in proper position at the 0 side of the bearing 76 by means of a key 78 cooperating with the hub 79 of the gear whereby to fix the same to the shaft. At itsother end this shaft 75 has mounted thereon a bevel gear 80 in mesh with a similar bevel gear 81 on what may be termed a cam shaft 82 extended longitudinally of the table at the back thereof,,si1ch shaft being supported and revoluble' in a pair of bearings 83, 83 fixed to the under surface of the table, and on the end of such shaft remote from the bevel gear' 81 I mount a comparatively large spur gear 84, Figs. 2-and 3, which is in mesh with a pinion 85 on a. short main drive shaft 86, the latter having loosely mounted thereon a driving pinion 87 adapted to be rotated from any suitable source of power by means of a belt not illustrated, and in order that such pulley may be brought into operative relation with the shaft 86 I provide the machine with a friction clutch 88 of any approved type, operable by means of a handle 89 protruding from beneath the table at the front of the machine, Fig. 2, and in order that the shaft 86 may if desired be turned manually.

I aflix to its outer end a hand wheel 90 of the usual type. 0 From the above description it will be. apparent to those skilled in this art that the power derived from the pulley 87 is used from the various shafts and gears described to rotate shaft 60 at a constant desired speed, and that the latter in turn occasions the intermittent rotation of the shaft 53.

The inner end of shaft 53 is provided with a carrier 91 in the present instance integral with the shaft 53, though this is not necessary since it is simply required that such carrier be fixed with the shaft to move therewith. Such carrier has four bifurcated arms 92, 92 disposed or arranged 90 apart, the spaced parts 93 and 94 of each of such arms being apertured in alinement at 95- and 96 to accommodate and form bearings for the hollow cylindrical extension or shank 97 which has at one end a rectangular form or block 98 slightly tapered at 99 for the reception and accommodation of the rectangu-' lar box rims. Between the spaced portions or parts 93 and 94 of each of these carrier arms 92 the hollow spindle or shaft 97 has shaft by a set-screw or otherwise, properly maintains the hollow shaft 97 from longitudinal displacement in its bearings, The cylindrical recess 101 in shaft 97 accommodates the coil expansion spring 102 bearing at one end against the end wall 103 of the recess, and'abutting at its other end against the inner surface of a sleeve or collar 104 fixed to the end of a rod 105 and conforming in external diameter to the bore of the recess 101. The rod 105, as is indicated, is sufliciently smaller in diameter than the recess 101 to provide sutlicient space for the accommodation of the spring 102, such rod extending through an aperture 106 in the box rim form 98 and adjacent portion of the shaft, and carrying at its end a plate pusher 107 normally retracted by the action of spring 102 on the rod 105 into the sligl'it de' pression or cavity 108 in the face of form 98, Fig. 10. As is clearly illustrated, the shape of this plate pusher is of cross conformation and the cavity or recess 108 is of substantially the same size and shape. In order to prevent this pusher from turning relatively to the form 98, rod 105 is equipped with a lengthwise groove 109 into which projects the inner end of a screw 110 fitted in the threaded hole of shaft 97. On that portion of the shaft 97 between the arm 94 and the rim form 98, I pivot on a screw 111 threaded into the shaft a clamp 112 (Figs. 5, 9, 12, 22 and 23) having a finger or end 113 adapted, under certain conditions, to overlap or engage the edge of the rim form as shown in dotted lines in Fig. 23, this clamp being pressed to such disk by means of a coil expansion spring 114 interposed between its other end and the adjacent face of rim form 98. The clamp is held in inoperative position as shown in full lines in Fig. 23 by means of an inclined cam 115 secured to the face of the part 94 by means of screws. Also on the arm 94 I pivot at 116 a lock arm 117 carrying at one end a lock pin 118 adapted to be projected into a hole 119 of ear 100, whereby to prevent rotation of said gear and the rim form 98. In order to maintain such lock pin in operative locking engagement with the gear, I interpose between the opposite end of the arms 117 and the carrier 91 an expansion spring 120 which by its action normally presses the pin into locking position with respect to the gear. As I have clearly illustrated, each of the four arms of the intermittently moved form carrier 91 is provided with a mechanism of this kind.

Referring now to that portion of the mechanism for applying the rectangular rims or sides of the pasteboard box to the various forms 98 as they are brought to proper position, it will be observed that a hollow plunger box 121 is mounted in any approved manner on the top of an inverted U-shaped standard 122 bolted to the top of table 50. This plunger box or shell is positioned in alinement with the rim form 98 in its uppermost position, and in which position it is temporarily maintained stationary by the Geneva movement or carrier actuating mechanism Box 121 is hollow, open at both ends, and has each of its inner side faces and its bottom wall provided with two parallel grooves 123. In such box or shell and adapted to slide therein, I employ a plunger or rim pu'sher 124 of general rectangular form in cross-section and substantially fitting the interior of the hollow box 121. On its two sides and on its bottom this plunger or pusher has ribs 125 adapted to tit and slide in the above-mentioned grooves 123, Fig. Such plunger or pusher 124 is adapted to apply or force the rectangular box rim 126, Figs. 5 and 24, to the tapered portion 99 of the form 98 in alinement therewith, and in order to actuate such plunger or pusher I provide a cam 127 on shaft 82, Fig. 3, and l fulcrum at 128 a cam lever 129, the lower end of which is supplied with a roller 130 traveling on the surface of such cam, the upper end of the lever being connected to the plunger 124 bya link or connecting rod 131. In order that these rectangular pasteboard box rims may be fed in succession to the hollow box or shell 121, I mount on top of the latter and above an opening 134 in the top wall thereof a magazine chute 132 open at the back and front at 133 and adapted to contain the box rims, 126, such rims resting one on top of the other.

It will be obvious that this magazine is adapted to feed these rims one after the other through the opening 134 to the box 121, and that the reciprocatory plunger 124 individually places such rims on the forms 98 as the latter are brought to position. As soon as the plunger returns sufficiently to open the passage 134, the rims above by their own weight drop so that another one is received in the box 121 in front of the plunger. To assist in this feed of the rims and to aid in maintaining them in rectangular form or shape, I supply the top of the box 121 with a pair of bearings 135 in which a shaft 136 may oscillate, Figs. 2 and 3, such shaft being equipped between the bearings with an arm or finger 137 fixed thereto and having its forward end projecting through the opening 133 of the magazine chute into the interior thereof, whereby such arm is enabled to engage the rims, assist in their downward travel, and aid in presenting them to the box 121 in rectangular form. In order to actuate this finger in proper timed relation to the movements of the plunger 124, I mount a downwardly-extended arm 138 on the protruding end of shaft 136, the lower end of such arm being. apertured at 139 and having U extended through such hole a bent rod 140 connected at the back end of the machine at 141 with a pivot pin between the rock arm 129 and against the parts 138 and 143. To return plunger 124 and to maintain the cam roller 130 in contact with its cam 127 I use a coil contractile spring 145 in the box or shell 121, Fig. 5, fastened at one end to the plunger 124 and at its opposite end to a pin or other suitable part 146 rigid with the box or casing. From an understanding of the con structionof this portion of the mechanism it will be apparent that assuming that the box rims are supplied by hand, or in any other manner, .to the magazine chute 132, the plunger will be reciprocatcd by its cam and connecting mechanism so as to force the rims one at a time on the various rectangular forms 98 which are brought in succession in front of the open end of the box or casing 121 and temporarily held in such position for the application of these rims,

due to the intermittent action of the rotary from carrier. \Vhen the plunger is retracted the next rim above falls by its own -weight-, or by the assistance of the action of the spring-pressed arnf'137 if such becomes necessary, into the box in front of the plunger, the other rims also descending and resting upon this lower rim. The spring" operated arm 137 assists in this downward travel of the rim, as explained, and also facilitates maintaining such rims in the desired rectangular form. If these rims have a tendency to bulge at the sides or bottom of the plunger box 121, they will nevertheless be forced into rectangular shape before application to the form 98 by reason of the inclined faces 121 on the inside of box 121, the box being larger some distance inwardly from its mouth than directly at its mouth, -so that the rims by traveling along the same are readily caused to assume proper rectangular or other form. If bulging of the rims occurs satisfactory discharge of the same from the box 121 will occur due to the pres ence of the protruding ribs 125 of the plunger, and attention might be directed to the fact that the plunger is of slightly less height than the opening inits containing box, so that if the top strip of the rim therein is concave or bent downwardly with the rim above resting in such depression, such upper rim will notbe fed forward or damaged as the plunger advances. After the rim has been applied to the form as described above, in the uppermost position .of such form, the carrier by the mechanism plied with a horizontal bearing 148, Figs.

11 and 13, which receives a hollow sliding cylindrical sleeve 149 preventing this turning relatively to the standard by means of a set-screw 150, Fig. 12, extended through the bearing into a key-way or groove 151 in the sleeve. At its forward end such sleeve is equipped with a box or shell 152 having a rectangular cavity 153 open at the end toward the form carrier. Sleeve 149 accommodates in its axial bore 154 a cylindrical rod 155 carrying at one end a rectangular pusher or plunger 156 in the cavity 153 of the shell or box 152. This plunger or pusher is reeiprocated by means of a cam 157 on shaft 82, such cam llaving'a cam slot 158 in one face in which travels a roller 159 secured to a link 160 having a forked end-161 straddling the shaft and pivoted at 162 at its other end to the lower arm of a lever 163 fulcrumed on the bracket at 164,

such lever at its top end having a pin and 4 slot' connection at 165 with the rod, and in order to interpose a cushion between such lever and rod I house in a cavity of the latter a coil expansion spring 166 pressing outwardly a small plunger 167 which bears against such lever, this construction. being clearly shown and illustrated in Fig. 13. Owing to this cushion or spring connection between the parts the elements are enabled to readily adapt themselves to variations in the thickness of the pasteboard stock' employed. The top wall of the box 01' Shell 152 has a slot 168 therein, and above the same a flaring chute or guide 169 is positioned. The slot 168 is adapted to be opened and closed by means of a sliding'plate 170 on the forward end of a sliding rod 171 reciprocatory in a suitable bearing 172 on the standard 147, such rod and plate being pressed forwardly into slot closing position by an expansion spring 173 positioned between the end of the rod and the standard.

The bottom side of plate 170 is equipped
